Application filed August 7, 1915. Serial no. trace.

To all wkom it may concern Be it known that I, FRANK O. Hnrms'rnoiu, acitizen of the United States, residing at Bismarck, in the county ofBurleigh and State of North Dakota, have invented a new and usefulHeating System, of which the following is a specification.

The device forming the subject matter of this application is a heatingsystem, and the invention aims to provide anovel means whereby the airwithin an apartment may be heated through the walls of the apartment, byradiation from the walls, there bebit ing no registers or flues openingfrom the heating system directly into the apartment which is to beheated.

it is within the province of the disclosure to improve, in particularsto be pointed out hereinafter, a heating system of the type abovementioned.

Withthe above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit oftheinvention.

In the accompanying drawing :'Fi gure 1 shows in cross section, abuilding wherein the present heating system has been installed; Fig. 2is a plan of the reinforcement which is used in connection with thewalls of the building. 7

in the accompanying drawing there is shown a building 1 of any desiredsize and form, embodying a foundation 2. The building 1 comprises aninner wall 3, an outer wall l and an intermediate wall 5. The walls 5and 3 define a passage 6 through which heated air is adapted to flowupwardly, the walls 5 and 4 defining a passage 7 through which the air,having been cooled more or less, flows downwardly.

All of the walls 3, a and 5 preferably are made up of superposed blocks8 arranged in horizontal courses. Lying between the courses of blocks 8and binding together the walls 8, 4 and 5 are reinforcements 9 ofopen-work construction, the reinforcements 9 being in the form ofexpanded metal laths, if desired. The reinforcements 9 serve to tie thewalls together, as hereinbefore stated, but, being of foraminous oropen-work construction, in nowise interfere to an appreciable extentwith the upward flow of hot air through the passage 6 and the downwardflow of cooled air through the passage 7.

'lhe ceiling of the building embodies an upper member 10 and a lowermember 11 between which is interposed a vertical partition 12, definingupon each side of the partition, passages 14 which communicate with theupper ends of the passages Band 7, the intermediate walls 5 preferablyterminating adjacent the lower member 11 of the ceiling.

The numeral 15 indicates a roof which may be of any desired constructionand the fioor is shown at 16, the floor 16 and the ceiling ll10 definingan apartment 22.

The floor 16 and the foundation 2 define a. basement 23 in which islocated a heater 17 of any desired construction, the heater in thepresent instance being shown as surrounded by a casing. 18, forming withthe heater, an air space 19. Conduits open through the inner wall 3 andthrough the casing 18 and communicate with the passage 6, the conduits20 being adapted to conduct the heated air from the heater 17.. Conduits21 lead from the lower portion of the casing 18 through the inner wall 3and through the intermediate wall 5 and communicate with the passage 7.

in practical operation, the air in the space 19 is warmed by the heaterl7 and passes by way of the conduits 20 into the passage 6. The airrises in the passage 6 and, having been cooled, descends through; thepassage 7 the cooled air being returned to the casing 18 through theconduits 21. In this manner, a continuous circulation is obtained andthe inner walls 3 are heated, the air within the apartment 22 beingheated by radiation from. the walls 3.

It is to be observed that no openings are 1. A building comprising anouter wall;

an inner wall of less height than the outer wall; superposed upper andlower ceiling members projecting respectively from the walls and forminga compartment commu= nicating with the space between the walls; anintermediate wall between the inner and outer walls and having its upperedge spaced from the upper eeihng member; a floor extended from theinner wall; a heater; a supply conduit leading from the. heater to thespace between the inner and intermediate walls; and a return conduitleading from the heater to the space between the outer and intermediatewalls; the inner wall, the lower ceiling member and the floor definingan apartment which is heated by radiation from the lower ceiling memberand the inner wall.

2. In a device of the class described, a

building comprising an'inner wall; an outer wall; an intermediate 'wall,the walls being made up of superposed courses; an openwork reinforcementlying between the courses; a heater; a conduit leading from the heaterto the space between the mner and intermediate'walls; a conduit leadingfrom the heater to the space between the intermediate and outer walls;and the upper ends of the intermediate wallsbeing open, to permit areturn circulation thereacross.

fiIn testimony that I claim the foregoing as my own, I have heretoaflixed my slgnature.
